error: failed to load manifest for workspace member `/builddir/git-cliff-0.4.2/git-cliff-core`

Caused by:
  failed to parse manifest at `/builddir/git-cliff-0.4.2/git-cliff-core/Cargo.toml`

Caused by:
  feature `edition2021` is required

  consider adding `cargo-features = ["edition2021"]` to the manifest

Is this really cause the toolchain is too old?
